Jon Heyman of SI.com reports that an MRI on the right shoulder of Huston Street came back “clean.” This at least eliminates the worst-case scenario of season-ending surgery or something of that nature, but according to Heyman, the club “will take it slow with him” and “look for another reliever.”

Obviously, Street’s chances of opening the season on time are in real jeopardy. Manager Jim Tracy has already expressed confidence in Franklin Morales, who filled in for Street last season while he was nursing a sore right biceps tendon injury in September.

Just about an hour before Heyman’s tweet, Ken Rosenthal of FOXSports.com reported that the Mets continue to talk with free agent left-hander Joe Beimel. Earlier today, Aaron mentioned the Rockies’ interest in Beimel as a second left-hander if Morales — the club’s most reliable southpaw out of the pen — assumes the closer role. Beimel, who turns 33 in April, posted a 4.02 ERA in 26 appearances with Colorado last season.
